Based on some testing it seems to me that if I have a package with
a dataset in /data
a Sweave vignette in inst/doc (but no associated pdf file)
the vignette loads the data in /data through
data(dataset)
and I do a
R CMD build
R will try to build the pdf version of the vignette, but will be
unable to find the dataset in data because the package is not yet
installed. However, if I do
R CMD build --no-vignettes PKGNAME
R CMD check PKGNAME_VERSION.tar.gz
the package passes R CMD check! Presumably because R CMD check
installs the package first.
This took me a long time to track down (inspired by a recent addition
of dataset to the Bioconductor package Genominator and a subsequent
failed build - specifically the dataset yeastAnno.sources and the
vignette withShortRead.Rnw). I am using lazy loading (in case it
matters, which I don't think it does).
It seems like the relevant fix is to include pdf versions of the
vignette(s) in inst/doc.
On one hand I can see why the build fails. And the fix is easy. But
just thought I would mention it.
